PHP DOMDocument error handling

Question

In my application I am loading xml from url in order to parse it. But sometimes this url may not be valid. In this case I need to handle errors. I have the following code:

Answer 1

From php.net

If an empty string is passed as the filename or an empty file is named, a warning will be generated. This warning is not generated by libxml and cannot be handled using libxml's error handling functions.

In your production environment you shouldn't have errors displayed to the user. They don't need to see them so taking this into account you can use...

$xdoc = new DOMDocument();
if ( $xdoc->load($url) ) {
    // valid
}
else {
    // invalid
}
